Norpro Perfect is your personal “egg oracle” that will predict the perfect degree of egg doneness without alarm clocks or timers! Throw it in the pan with the eggs and it will tell you when the eggs are ready - from soft to hard. Its secret - it feels the heat like a real egg and changes color so you know the exact degree of doneness. Whether you boil 3 eggs or 10, it will take it all into account on its own! No more soggy surprises or overcooked “rubber bands” - just perfect eggs every time!
